DETAILED DESCRIPTION
[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection solution of the present invention.
[0026] The rainwater drainage structure is an important part of the urban drainage system, which is mainly responsible for collecting and discharging rainwater to prevent urban waterlogging. When it rains heavily, the grate outlet (also called the rainwater outlet or drainage outlet) is easily blocked. This is because when the precipitation is large, the flow rate of rainwater increases rapidly. The strong rainwater scouring will bring the surrounding soil, leaves, plastic bags and other debris to the grate outlet, causing the grate outlet to be blocked.
[0027] Existing rainwater drainage structures generally include a rainwater inlet, a garbage basket, and a drainage pipe, wherein the rainwater inlet is arranged at the edge of the road to collect rainwater flowing into the rainwater drainage structure, a grate is arranged at the top of the rainwater inlet, and the grate can prevent large debris, such as large leaves, plastic sheets, etc. from entering the rainwater inlet, a garbage basket is arranged inside the rainwater inlet to filter small garbage, such as stones, small leaves, etc., and the drainage pipe is used to discharge the rainwater that finally flows into the bottom of the rainwater inlet into the rainwater main pipe, and finally into the receiving water body such as the river.
[0028] At present, this kind of rainwater drainage structure can easily cause large garbage to block the grate opening when the rainwater is too heavy, thus affecting the normal rainwater discharge.
[0029] The present invention discloses a rainwater drainage structure, such as Figure 1-Figure 3 As shown, it comprises: a rainwater inlet 1, a first debris storage box 6 and a first debris processing unit; wherein a vertical partition 2 is arranged in the rainwater inlet 1, and the partition 2 divides the rainwater inlet 1 into a drainage cavity 4 and a functional cavity 3, and a grate 5 is arranged on the top of the functional cavity 3, and a strip-shaped drainage outlet is arranged on the grate 5; the first debris storage box 6 is arranged on the functional cavity 3, and a first strip-shaped groove connected to the top of the drainage cavity 4 is arranged on the side wall of the first debris storage box 6; the first debris processing unit comprises a first sliding block 7 and a cleaning rod 8 The first sliding block 7 is slidably arranged in the drainage cavity 4 and can slide along the direction of the drainage outlet. A plurality of cleaning rods 8 are arranged on the first sliding block 7. The number of cleaning rods 8 corresponds to the vertical direction of the drainage outlet. Therefore, the cleaning rods 8 can be used to scrape away the large garbage at the drainage outlet and above the drainage outlet. Finally, the large pieces of garbage are scraped into the first sundries storage box 6 on one side. After that, the first sliding block 7 moves back and forth to clean the large garbage at the drainage outlet on the grate 5 to prevent the large garbage from clogging the drainage outlet of the grate.
[0030] The bottom of the drainage cavity 4 is also connected to a drainage pipe for draining rainwater at the bottom of the drainage cavity 4 into the rainwater main pipe.
[0031] When it rains heavily, the grate opening is easily clogged. Therefore, in order to enable the first sliding block 7 to automatically move and drive the cleaning rod 8 to clean up the garbage when it rains heavily, the bottom of the first sliding block 7 disclosed in this embodiment is provided with a driving unit that can drive the first sliding block 7 to automatically perform reciprocating linear motion. The driving unit includes an impeller assembly and a first transmission assembly. The impeller assembly is arranged in the drainage chamber 4 and is located below the grate 5. When rainwater passes through the drainage port on the grate 5, the impeller assembly can be driven to rotate. The first transmission assembly is arranged in the functional chamber 3 and connected to the impeller assembly. The first transmission assembly is also connected to the first sliding block 7. When the impeller assembly rotates, the first sliding block 7 can be driven to perform reciprocating linear motion through the first transmission assembly. Therefore, when rainwater flows down from the drainage port of the grate 5, it falls on the impeller unit arranged in the drainage chamber 4, and then the water flow drives the impeller unit to rotate. The impeller unit drives the first transmission assembly and the first sliding block 7 to move in turn, and finally drives the cleaning rod 8 on the first sliding block 7 to move and clean up the garbage in the drainage port. Therefore, when it rains heavily, as long as rain falls on the impeller unit, the first sliding block 7 can drive the cleaning rod 8 to move back and forth to clean the garbage on the grate 5.
[0032] Furthermore, in order to ensure that the garbage on the grate can fall normally into the first sundries storage box 6 when it is pushed to one side edge of the grate, the upper end of the cleaning rod 8 disclosed in this embodiment is provided with a guide rod 18 which is perpendicular to it and points to the first strip groove, so that the guide rod 18 can introduce large garbage into the first sundries storage box 6.
[0033] like Figure 2 As shown, the impeller assembly disclosed in this embodiment includes an impeller 9, a rotating disk 10, a rotating shaft 11 and a plurality of driving shafts 12. The rotating shaft 11 is horizontally arranged between the drainage chamber 4 and the functional chamber 3 and one end of which is connected to the inner wall of the functional chamber 3. The rotating disk 10 is arranged on the rotating shaft 11 and is located in the drainage chamber 4. The plurality of driving shafts 12 are circumferentially arranged on the rotating disk 10. Each driving shaft 12 is provided with an impeller 9. Therefore, a plurality of impellers are circumferentially arranged on the rotating disk 10. The water flow on the upper side of the grate 5 will fall from three different directions. As long as water falls on any impeller 9, the impeller 9 will drive the rotating disk 10 and the rotating shaft 11 to rotate, thereby driving the first transmission assembly and the first sliding block 7 to move in sequence through the rotating shaft 11.
[0034] The first transmission assembly disclosed in this embodiment includes a first bevel gear transmission group and a first crank slider component, the first crank slider component is arranged on one side of the first sliding block 7 and is connected to the first sliding block 7, the first bevel gear transmission group is arranged between the impeller assembly and the first crank slider component, and when the impeller assembly rotates, it drives the first bevel gear transmission group and the first crank slider component to move in turn, thereby driving the first sliding block to perform reciprocating linear motion. The specific first bevel gear transmission group includes a first support shaft 19 arranged in the functional cavity 3 and perpendicular to the rotating shaft 11, a first bevel gear 20 is arranged on the rotating shaft 11, a second bevel gear 21 meshing with the first bevel gear 20 is arranged on the support shaft 19, the first crank slider includes a first crank 22 and a first connecting rod 23, the first crank 22 is arranged at the upper end of the first support shaft 19, the first connecting rod 23 is hinged to the first crank 22, and the end of the first connecting rod 23 away from the first crank 22 passes through the partition and is connected to the first sliding block. Therefore, when the rotating shaft 11 rotates, it drives the first bevel gear 20, the second bevel gear 21 and the first support shaft 19 to rotate in sequence. The rotation of the first support shaft 19 drives the first crank 22 to rotate, thereby driving the first connecting rod 23 to reciprocate through the first crank 22, and finally realizing the reciprocating linear motion of the first sliding block 7 set at the end of the first connecting rod 23, so that the first sliding block 7 drives the cleaning rod 8 to reciprocate linear motion and cleans the garbage on the upper side of the grate.
[0035] In order to make the impeller rotate better, three driving shafts 12 are arranged on each rotating disk 10 disclosed in this embodiment; when the impeller on any one of the driving shafts 12 rotates, the rotating disk 10 will be driven to rotate.
[0036] When the rainwater continues to flow downward through the grate, there will be small particles of garbage such as stones and sand in the rainwater. In order to clean up these garbage and prevent these small particles of garbage from affecting the discharge of rainwater, the bottom of the impeller assembly disclosed in this embodiment is also provided with a filter screen 13, and a second debris processing unit for processing debris on the filter screen 13 is provided above the filter screen 13. The second debris processing unit includes a second sliding block 14 provided above the filter screen 13, and a cleaning brush 15 is provided on the second sliding block 14. Therefore, when the second sliding block 14 moves back and forth and drives the cleaning brush to move back and forth, the small particles of garbage filtered out by the filter screen 13 can be cleaned. A second debris storage box 17 corresponding to the filter screen 13 is also provided in the functional cavity 3, and a second strip groove corresponding to one side of the filter screen 13 is provided on the side wall of the second debris storage box 17. Therefore, the small particles of garbage on the filter screen 13 can be eventually moved to the second debris storage box 17 by the cleaning brush, thereby avoiding a large amount of garbage accumulation on the filter screen 13 and affecting the normal discharge of rainwater.
[0037] An inclined impurity guide plate 18 connected to one side of the filter screen 13 is provided at the second strip groove, the upper side of the guide plate 18 is connected to the filter screen 13, and the lower side of the guide plate 18 points to the second debris storage box 17; therefore, when the small particles of impurities on the filter screen 13 are sorted by the cleaning brush to one side edge of the filter screen 13, the small particles of impurities finally slide into the second debris storage box 17 through the impurity guide plate 18.
[0038] The second sliding block 14 disclosed in this embodiment is provided with a second transmission assembly for driving the second sliding block 14 to perform reciprocating linear motion on the upper side thereof, the second transmission assembly comprising a second bevel gear transmission group and a second crank slider component, the second crank slider component being arranged at one side of the second sliding block 14 and being connected to the second sliding block 14, the second bevel gear transmission group being arranged between the impeller assembly and the second crank slider component, and the impeller assembly driving the second bevel gear transmission group and the second crank slider component to move in turn when rotating, thereby driving the second sliding block 14 to perform reciprocating linear motion. The specific second bevel gear transmission group comprises a second support shaft 24 arranged in the functional cavity 3 and perpendicular to the rotating shaft 11, the second support shaft 24 being arranged below the rotating shaft 11, a third bevel gear 25 meshing with the first bevel gear 20 being arranged on the second support shaft 24, the second crank slider comprising a second crank 26 and a second connecting rod 27, the second crank 26 being arranged at the lower end of the second support shaft 24, the second connecting rod 27 being hinged to the second crank 26, and the end of the second connecting rod 27 away from the second crank 26 passing through the partition and being connected to the second sliding block 14. Therefore, when the rotating shaft 11 rotates, the first bevel gear 20, the third bevel gear 25 and the second support shaft 24 are driven to rotate in sequence, and the rotation of the second support shaft 24 drives the second crank 26 to rotate, thereby driving the second connecting rod 27 to reciprocate through the second crank 26, and finally realizing the reciprocating linear motion of the second sliding block 14 arranged at the end of the second connecting rod 27, so that the second sliding block 14 drives the cleaning brush 15 to reciprocate linear motion and clean the garbage on the upper side of the grate. Therefore, as long as it rains heavily and rainwater falls on the impeller unit, the second sliding block 14 can reciprocate and drive the cleaning brush 15 to clean the small particles of impurities on the filter screen 13, so that there will be no garbage accumulation on the filter screen 13, and it will not affect the normal drainage of rainwater.
